'IG ALL WHOM IT'MAY' CONCERN:

Be it yknown that I, E. L. HAGAR, ofEiupre City, in' the county of Clear Creek, and Territory of Colorado, have made and invented a new and useful Improvement in Chart or Map-Roller; and I do hereby declare that the-following is afull, clear, `and exact description thereof, which will enable -those skilled in the art to make and use'the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The present invention relates to a roller for maps and other similar charts, and it consists in arranging the V' roller therefor within a case, that is suitably constructed to allow the map or other chart attached thereto to be rolled up or unrolled at pleasure, through and by' means of cords and tassels, or other suitable devices, the saidcase, when the charts are rolled up,'encasing the same,and protecting them from being soiled or injured.

In the accompanying plate of drawings,V my improved ioller for charts, tc., `is illustrated- Figure 1 being a front vieni of the same, and l j Figure 2 a transverse vertical section, taken in the plane ofthe line x zr, iig. 1.

A, in the drawings, repre'sentsmy improved roller-device for maps and other charts, which, in the present instance, consists-of two rollers B within a. case, C, arranged so as to turn therein, and each-roller provided with I a map or chart, D, around which they are wound, and passing out, when unwound, through the opening E in the bottom of the said case C.

H a cover to case C. This cover is hinged thereto, yso as to be susceptible of being opened and closed atv pleasure for an inspection and removal or insertion fof the rollers B, as may be desired.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The chart-roller constructed as described, consisting' of the case C having the hinged lid H, and adapted to receive the chart-rollers B, said chart passing through the curved opening E, their operating-cords F passing through separate openings in -front of the charts, as herein shown and described.
